Field
Set at reception of the first packet on the RX Connection Structure.
Loss of one or many RTP packets detected because the sequence number fields of two
consecutive packets were not incremental. The Previous and Current Sequence
Numbers will indicate number of lost packets.
This bit is set when the R bit is set in the RX Channel Structure Split Entry (as taken for
the packet).
Bad Packet Length 1. When set, a packet has been received with insufficient bytes to
contain an RTP header. It will be discarded entirely.
RTP Version Mismatch. When ‘1’, this means that a packet was received with RTP
version not equal to 2.
UDP Checksum Error. When set, a packet has been received with an incorrect UDP
checksum.
Base address of the RX RTP Connection Structure that generated this report structure.
Theses two fields contain the value of the Marker bit and Payload Type of the RTP
packet that caused this error structure to be generated.
This field contains the length of the UDP payload of the received packet that caused this
structure to be generated. If the UDP Payload is longer than 255 bytes, this field will be
saturated at value 255.
RTP Sequence number of the second last packet that was received.
RTP Sequence number of the last packet that was received.
Local Bus Time Stamp present at the time of reception of the packet that caused this
report structure to be generated.
